Abstract
A thermoplastic resin composition composed of a mixture comprising: PA0 (A) from 5 to 94% by weight of an elastomer-containing styrene resin comprising an elastomer component and a resin component having a glass transition temperature of higher than 20.degree. C., with a covalent substance of the elastomer and resin components being present at the interface between the elastomer component constituting a dispersed phase and the resin component constituting a continuous phase; PA0 (B) from 5 to 94% by weight of a polycarbonate resin; and PA0 (C) from 0.1 to 20% by weight of a polymer of a monomer containing an acrylate monomer having a solubility parameter of from 8.4 to 9.8 (cal/cc).sup.1/2, a glass transition temperature of not higher than 20.degree. C. and a gel content of not higher than 70% by weight.
